FEEDING DEVICE FOR CARDING-ENGINES.

SPECIFICATION forming part of Letters Patent No. 263,161, dated August 22, 1882,

` l Application filed March 17, 1882. (No model.)

To all whom 'it may concern:

Be it known that I, JonN F. GEBHART, of New Albany, in the county of Floyd, and in the State Indianahave invented certain new and useful Improvements in Feeding Devices for Garding-Engines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanyin g drawings, and to the letters of reference marked thereon, making a-part of this specification, in which- Figure 1 is plan viewr of the feed-table, the traveler, the bowed equalizing-rod, and the shifting devices for the feed andl distributing rollers, showing also lines of roving distributed onl said feed-table. Fig. 2 is a front elevation of Fig. l. Fig. 3 is an enlarged horizontal section through the traveler, indicating the smooth feed-rollers. Fig. 4 is a vertical crosssection through the rack, the frame, and guide-rod, indicated by dotted line c; sc, Fig. 2, showing an edge view of the traveler.

This inventionrelates to machinery which is designed for preparing fibrous substances (especially wool) for spinning; and my object is mainly to obtain a perfect and reliable mechanism for feeding second breaker and condenser carding-engines and to obtain acontinuons uniformity of the prepared sliver or roving during the process of laying it in parallel serpentine rows upon an endless feed-table.

In machines of this class as hitherto constructed a very serious defect exists, in that the wool is unevenly distributed upon and across the feed-table of the engines.

The following description ot' my invention, when taken in connection with the annexed drawings, will enable others skilled in the art to fully understand it.

In the annexed drawings, the letterA designates the feed-table, which is composed of a frame and a number of narrow endless bands or aprons of different lengths passed around rollers at opposite ends of the table.

Obliquely across the front end of the feedtable A is a horizontal frame, B, which is mounted on standards at its extremities, and is arranged in -a horizontal plane parallel to the top of the said feed-table, at a suitable distance above the same.

Along the lower front side of the frame B is -a toothed bar or rack, C, and below this rack is a ,smooth edge bar, D, which is flush with `the ends of the rack-teeth.

The extremities of the frame B are curved upward andconnected together by mieans ot' a horizontal rod, E, on which traverses the distributing-traveler F, which is composed of the several parts hereinafter named. The rectangular depending portion of'the traveler F has a vertical slot, a, through it, in which plays freely a stud, b, that projects from the edge of an endless belt, Gr. This belt Gis carried-on pulleys c c, projecting from the face of the frame A, one of which pulleys is rotated by mechanism engaging with a pinion, J2, thus giving a continuous motion to the said belt and a reciprocating rectilinear motion to the traveler F, the latter traversing the entire length of the frame or feed. The lower end of the traveler or traveling guide F has :applied to it two vertical toothed drums, H H, which are free to rotate. The upper toothed portion, c, of said drums H engages with the teeth of the rack O, the annular grooves e' bear, by their smooth peripheries, against the straight edge of the bar D below said rack, and the toothed or serrated portion e2 of the drums H H rotates in contact with two smooth surface frictionrollers, J J, and thus gives rotation thereto.

K designates a horizontal plate, which is connected to the traveler F by means of curved vibrating arms ff, that are pivoted at their extremities to said parts, as shown in Fig. 1.

These curvedor segmental arms f f allow the plate K to be shifted endwise to the right or left by means hereinafter explained.

The smooth or plain faced rollers J J turn on vertical studs fixed to the bottomi of the plate K, and in front of these rollers a piece, L, is applied, which is rigidly secured at its upper end to the plate K.

Through the center of the piece L is a funnel-shaped eye, g, which vdirects and guides the roving between the rollers J J. y

The front edge of the plate K is concave, and against this concave edge bears a spring, N, which is secured fast to the top of the trav eler F. By forming the concave depression in the face of the plate K, as described, I relieve the spring or obtain an even tension when said plate is shifted at the ends of the feed.l By the pressure of the spring N against the plate K either one or the other of the smooth rollers J, as the case may be, will be held against one or the other of the serrated porltions. e2, thereby securing a feed of the roving between said roller and wheel.

The drawings, Fig. 3, show a roving passing through the funnel-eye g and between a roller J and portion e2, in which position of the parts the'traveler will be moving in the direction indicated by the arrow. When the traveler is moved in an opposite direction vthe opposite roller and feed-wheel will be brought into action, as hereinafter explained.

At the extremities of the feed or feed-table A, and pivoted to posts M M, are hooks P P, which are supported upon stops h h in position for operation.

At the middle of the length of the plate K a fiat stud, fi, is secured, which, when the traveler reaches the terminus of each stroke, is engaged by ahook, P. When the traveler starts on its return-stroke the said engaged hoolr will shift the plate K and change the relative positions of the smooth and toothed rollers. After this shifting of the rollers a cam or V- shaped tooth, j, formed on an arm of each hook P, will be brought in contact with a pin, lc, on the traveler F, which will cause the hook P to release the lu g or stud t. The traveler will then proceed on its way across the feed-table and deliver a line of roving evenly 011 the endless apron.

In practice I x into the bottom of the guide-bar D, near its ends, several short pins, l,

(shown in- Fig. 2,) which will catch the roving and temporarily arrest it until the traveler has proceeded the required distance, when the roving will of itself drop free from the studs. Thesev short studs or pins l may be pitched backward. These pins allow the roving to drop by its own weight after the traveler has moved a short distance. They check the roving at the termini of the strokes of the traveler, so that the roving will be laid evenly at the sides of the feed-table. It' the pins lare slightly pitched back, they will more positivel catch and shed the roving. v

R designates' a rod which is arranged in front of the feed and traveler and extended from end to end of the feed-table A. This rod is bowed, as shown in Fig. 2, when the roving is fed from above beneath it, and it is secured at its extremities rigidly to said table..` This rodl will, by reason of its curvature, equalize the friction and tension of the roving as it passes under it on its Way to and through the eye g, above described. lf the roving is fed over the rod R, the latter should be bowed upward or ina reverse manner to that shown in Fig. 2. The bowed guide-rod R will, by reason of ,its curvature, take up the slack of the roving ou its Way to the eye of the traveler. When the distributer of the roving is arranged on the door or beneath the bed A the curve or bow of the said rod will be up. When the roving-distributer is above the bed A the curve of the rod It will be down. It is of course understoodv that the point of delivery of the roving to the said rod is at the middle of its length.

The belt G is or may be operated from the carding-inachine in the same manner as the ordinary Apperly and Glusmered feeder.

Having described my invention, I claiml. The combination of the traveler F, mechanism for reciprocating the same, its toothed drums, a rack-bar, a feed-table, the shifting plate connected by pivotedarms to said traveler, and the smooth rollers receiving rotation, substantially in the manner and for the purposes described.

2. The combination, with the traveler arranged to reciprocate over the feed-table, and

means for moving this traveler, of the toothed drums, the shifting plate bearin g feed-rollers, and an eye piece or guide for the roving, and a spring acting on the curved edgeofthe said plate, substantially as described.

3. The combination of shifting hooks and releasing devices therefor with a traveler bearing toothed drums, and a shifting plate having feed-rollers applied to it, substantiallyv as described.

4. The combination, with the traveler F, of the `annularly-grooved toothed drums H E, the rack which engages lwith the upper teeth of said drums, the smooth-edge guide railor bar applied beneath the rack and receiving the grooved parts of the drums, the smooth feedrollers, a spring for holding said rollers against the drums, and shiftin g devices for the plate K, all substantially in the manner and for the purposes described.

5. The combination, with the bar D and pins l, arranged at the ends of said bar, of the traveler and means for reciprocating the same, said traveler being adapted to feed and 'distribute the roving upon the endless feed-apron, substantially as and for the purposes described.

, In testimony whereof I affix my signature, in presence of two witnesses, this 17 th day of February, 1882. l
